, Specification of Letters Patent.

To all whom it may concern Be it known that I, WILLIAM HENRY LINDSAY, asubject of the King of Great Britain, residing at Johnstone, Scotland,have invented certain new and useful Improvements in and Relating toSelf-Lubrieating Bearings for Shafts, of which the following is aspecification. This invention relates to bearings for shafts of the typehaving a ring or collar upon and revolving withthe shaft and means forarresting lubricant rollable on the periphery of the ring or. collar. In

-such bearings the lower side ofthe ring or collar-dips into an oilwell, and,'as the ring carries. a certain 'amountof oil revolves, it

oil being arrested by around with it this the rollable means and causedto -flow down on to the shaft. The rollable means is preferably a smallroller. J 1

. .Under this invention the parts are so arranged that theroller doesnot occupy a central position abovethe ring or collar but always. restsat one side. or other of the center line. It is carried betweencurvilinear guides and is capableof moving into position at one side orother of the center line according to the direction of revolution oftheshaft. The, roller is automatically moved from the one position to' theother by the action of the collar. Owing to the fact that the rollerassumes aposition out of the center line it causes-the oil, carriedupward by the collar, to pile up to a certain extent and therefore downonto the brasses. The collar which has a A shaped periphery is made inparts preferably secured together by'spring split pins or the like. Theroller has a V groove so that its periphery is correlative to that ofthe collar.

In order that the invention may be clearly v understood I have hereuntoappended explanatory drawings whereon I have shown, by way of example, amode of carrying the invention into effect -or practice.

On the drawings Figure 1 is a sectional bearing. I

The-segments are securedtogether bymeans of spring split pins e, of which there may be four, these splitpins being compressed and then pushed through taper holes in thesegments andallowed to expand thus locking th'e'segments one of thesplit pins is shown in section and in position.

from the roller and these pins! can turnfreely in curvilinear guides g,g ,'depending from and forming part of a cover 15. sothat, when thecover. is removed, the roller can be moved along with it. It will beseen that, at the undersideof the guides, a gap is" left, as shown atFig. 2, and this allows, the oil or other lubricant which isarrested bythe roller and piled up in front of it to ass freely down either side ofthe collar 05 and thence. on to inclines'i, i, on the brasses It andalong the ducts j to thelubricating holes i in said brasses; 1 i y 7When the shaft 0 is'- rotated in an anticlockwise direction (Fig. 2) therollerf will rest in its guides, at th'egleft 'handfsiide of the centerline'11, representinga vertical plane through thejshaft-iaxis its'centerbeing on the line 2-2, r clined plane througlf-- tli shaft ax1s, butwhen the shaft is reversed the roller will be carried over to'theopposite side and rest shaft, the collar being tightened by compress-Senting' an in-' receptacle for lubricant, lubricant carrying selflubricating bearing therefor,
